Banchandeungsok is a book written by a person who lived in the Cheongju area located in northern Chungcheong Province. The literature is regarded as a useful source for showing types of local food in the 1910s, so it was purchased by the National Folk Museum in 2007. The writer categorized dishes described in the recipe section of the book into side dishes, snacks, rice cakes, drinks, and miscellaneous. Following this, each category was distinguished by the name of the dish, the main material, the side material, and the cooking method is presented in tables. Thus, the food culture of Chungcheong Province was arranged based on the above categorized contents. The material from the product and the outside which grow spontaneously divided with the product which flows. The case which is a product the outside, went through what kind of process and could flow toward Sangshin village in Cheongju area probably, to observe tried. The area and time were clear Eumsikdimibang and Gyuhapchongseo Jusigui with comparisons. So tried to observe the time of 1910's Cheongju area culture Dietary life time and a regional feature.

The purpose of this study was to compare the nutritional meal variety of self-selected diet in Korean adults with different age groups. Subjects were recruited and divided info three groups according to the age, which included 20$\sim$49 yrs group(n=129), 50$\sim$64 yrs group(n=134), and $\geq$65 yrs group(n핀8). Subjects were interviewed using a general questionnaire and 24-hour recall method for dietary intake. The average age of the subjects were 40.8 years for 20$\sim$49 yrs group, 57.1 years for 50$\sim$64 yrs group, and 70.7 years for $\geq$65 yrs group. The daily food, energy and nutrient intakes ere decreased with increment of age. The intakes of vitamin B2, folate, vitamin C, and calcium were under the 75% of RIs, respectively. The numbers of food items in diet of 20$\sim$49 yrs group, 50$\sim$64 yrs group and $\geq$65 yrs group were 14.2, 17.0, 13.2 for breakfast, 16.3, 15.4, 13.5 for lunch, 13.1, 15.1, 13.9 for dinner, respectively. And the numbers of dish items in these groups were 4.0, 4.6, 3.8 for breakfast, 4.4, 4.2, 3.9 for lunch, 4.0, 4.0, 3.6 for dinner, respectively. The KDDS of 20$\sim$49 yrs group, 50$\sim$64 yrs group and $\geq$65 yrs group were 3.9, 3.6 and 3.4 respectively and there was significant difference(p<0.001). According to these results, it could be suggested aged group take a undesirable meal in the right of insufficient nutrient intake to DRIs and lower food and dish items, and therefore showing a strong need of proper dietary management for them.

The purpose of this study is to evaluate the phenomenon of attachment and spreading of the cultured rat　calvarial cell inoculated on their surface of different kinds of biodegradable membrane which had been used on tissue regeneration on periodontal defects by using scanning electron microscope. In this experiment 30 Sprague-Dawley male rats (mean BW 150gm) were used to harvest abundant number of cell in the short period. The rats were sacrificed by decapitatioan to obtain the calvaria for bone cell culture. Calvarial cells were cultured with Dulbecco's Modified Essential Medium contained with 10% Fetal Bovine Serum under the conventional conditions. Biodegradable barrier membrane were collected with collagen type, and were divided into 3 different kind of surface such as scattered, polarized and fine-net type as their surface texture. Microcover plate which usually used for cell culture was used as control for smooth surface. All the membrane were seeded with cultured calvarial cell on their surface. The number of cell inoculated on the membrane were $1{\times}10^6$ Cells/ml. After the culture as designed time, all the membrane were washed with 0.1 M Phosphate Buffered saline and fuxed with 2.5% Glutaraldehyde. And all specimen were treated with $OsO_4$, and Tannic acid before drying the cell for coating the cell with gold. Scanning Electron Microscope was used to observation. The following results were obtained. I. During the whole period of experiment, the phenomenon of cell attachment and spreading were revealed similar pattern to compare with smooth surface culture plate and ordinary culture dish. 2. The shape of cell attachment and spreading on the surface of barrier membrane were observed no remarked difference pattern between smooth surface culture plate and ordinary culture dish. 3. The cytoplasmic process of cultured calvaria cell extent to the deep portion of barrier membrane like as their own proper shape. 4. There were no remarkable relationships between the degree of cultured cell spreading and surface structure of barrier membrane. 5. Slight starified layer of cultured calvaria cell were observed on the scattered type of resorbable membrane, Conclusively, this study thus suggest that cultured bone cell inoculated onto the biodegradable barrier membrane may have an important role of carrier for many cell which could be used as new tissue regeneration, and those tissue engeering technique may become an new method in the approach to the repair of bone defects.

The objective of this study was to develop a semi-quantitative food frequency questionnaire (FFQ) for an adult population for use in the Korea National Health and Nutrition Examination Survey (KNHANES). The 24-hour recall data for 2,939 subjects aged 19 years and over from the fourth KNHANES first year (2007) were used to extract the items included in the questionnaire. The FFQ items were developed by selection of major dishes based on the cumulative contribution rate, between-person variability based on the cumulative R2 of energy and 14 nutrients (carbohydrate, protein, fat, crude fiber, calcium, phosphorous, iron, sodium, potassium, vitamin A, thiamin, riboflavin, niacin, and vitamin C) and the number of consumers of each dish. In addition, the FFQ items were revised with analysis of 24-hour recall data of the fourth KNHANES second and third year (2008, 2009). Finally, 112 items were included in the FFQ and grouped as follows: rice (5 items), noodles and dumplings (6), breads and rice cakes (8), soups and stews (12), soybeans, eggs, meat and fish (23), vegetables, seaweed and potatoes (27), milk and dairy products (4), fruits (13), beverages (5), snacks (6) and alcoholic beverages (3). The food items of FFQ accounted for an average of 87.0% of energy and 14 nutrient intakes and also accounted for 81.7% of the between-person variability. The frequency range of the FFQ items was classified into nine categories (never or seldom, once per month, 2-3 times per month, once per week, 2-4 times per week, 5-6 times per week, once per day, twice per day and three times per day) and the portion size was divided into three categories (small, medium and large). We expect that this developed dish-based FFQ could be used in assessment of longterm dietary intakes of Korean adults.

The main purpose of this study was to improve the efficiency and quality of in vitro embryo production in Korean Native Cows (KNC). We examined the effects of ovarian morphologies (Experiment 1) and the culture vessel (Experiment 2) on in vitro maturation (IVM). We measured the subsequent development rates and cell numbers of blastocysts. In Experiment 1, the ovaries of KNC were divided into six groups, based on follicle and corpus luteum (CL) morphology. The development rates to the 2- and 8-cell stages were similar among the six groups. The development rates to blastocyst stages were significantly higher in the group without a CL or follicle (WOCL/F) than in the groups with follicular cysts (FCs), regressive CLs (RCLs) or cystic CLs (CCLs) (p<0.05). The cell number of the inner cell mass (ICM) of blastocysts in the FCs and RCLs groups, and the number of cells in the trophectoderm (TE) in the WOCL/F group, FCs, growing CLs (GCLs) and RCLs were significantly higher than in other groups (p<0.05). The total cell number (TCN) in the WOCL/F, FC and RCL groups was also significantly higher than in other groups (p<0.05). The ICM cell number/TCN ratio was significantly higher in the FC and RCL groups than in the GCL and DF groups (p<0.05). In Experiment 2, oocyte IVM was carried out in culture dishes, in 0.25- or 0.5-ml straws used for freezing sperm. The development rate to the 2-cell stage was significantly higher in the 0.5-ml straw group than in the 0.25-ml straw group. The development rates to the blastocyst stage were similar in the dish and the two straw groups. There were no differences in the cell numbers of ICM, TE or TCN or ICM cell number/TCN ratios between groups.

The purpose of this study was to analyze and evaluate dietary intake between with and without hypertension. Study subjects were more than 30 years old adults (n = 3,806) who participated in the 2001 Korea National Health and Nutrition Examination Survey. People who have 'self-recognition about hypertension' and 'having diet for hypertension' were excluded. Using the WHO standard, subjects were divided into the hypertensive group (SBP> 140, DBP> 90) and the normal group (SBP< 140, DBP< 90). The Body Mass Index (BMI) and the Waist-Hip Ratio (WHR) of a hypertensive group were higher than those of a normal group (p < 0.01). The distribution of the subjects for smoking, alcohol consumption, exercise, stress, preference of salty food were not significantly different between a normal group and a hypertensive group (p>0.05). Dietary intakes were investigated by the 24-hour recall method. When food and dish intakes analyzed by sociodemographic factors, normal group consumed more fruits than those of a hypertensive group. Statistical significant were shown at female group, residences in metropolitan area and having elementary school education (p<0.05). Hypertensive group consumed more alcoholic beverages than those of a normal group at 'age 39-39', 'aged 50-64', 'high economic status', 'low economic status' and 'residences in metropolitan' (p<0.05) The amount of intakes for fat, potassium, thiamin, vitamin C and alcohol were significantly different between the normal group and the hypertensive group (p<0.05). The highest score of the Dietary diversity score (DDS) was 4 in both normal group and hypertensive group. Normal group showed high Nutrition Density (ND) of vitamin C and hypertensive group showed high ND of sodium. In summary, these results showed that significant difference for people with hypertension were intakes of fruits, alcohol, thiamin, vitamin C. And these results differed by sociodemographic groups. Therefore, the differential approach in each group is demanded for prevention and control of the hypertension.

This study was conducted to find the number of meals skipped and the types of main meals consumed by people in Miryang and Daegu. The subjects consisted of elementary school students(ES), middle school students(MS), high school students(HS), college students(CS) and adults, divided into below the age of 40(AU) and above the age of 40(AA). Data were collected through a 7-day dietary record from 941 subjects. The definition of rice-based meal(RM) and wheat-based meal(WM) depends on the type of grain eaten in the main dish, rice or wheat flour, respectively, regardless of the menu. Out of all the meals consumed by the subjects during 7 days before the survey, 71.5% of the meals consumed were RM, 13.1 ％ of the meals consumed was WM and 12.5% of the meals was skipped. Of the meals skipped, breakfast-skipping was the highest with 27.1%. There's no difference by region and sex. But there were several differences by age. The rates of skipped meal were high for CS, AU, HS, and MS in order. Especially the breakfast-skipping for CS was highest as 47.9%. In the types of main meal, the rates of RM was highest at breakfast and lowest at lunch. The rates of RM was higher in Miryang than Daegu, and there was no difference by sex. The rates of RM was high for AA, HS, ES and AU in order. ES and HS, who had highest rates of WM, had the highest WM consumption at lunch. It is because of school food service at lunch. Since the younger population consumed more RM compared to the older population, it can be speculated that more WM will be consumed in the future. Also efforts need to be made to discourage skipping meals.
